The predictive role of preverbal gestural communication for the development of language and preschool skills: A longitudinal study emphasizing language delay and bilingualism

建议将已经由DFG资助的赠款继续用于对12至30个月的儿童进行一项长达6岁的纵向研究，以便a)进一步验证关于在言语前年龄识别语言障碍的可能性的线索；b)更详细地调查手势和语言技能关联的决定因素；以及c)验证双语样本中的结果。对儿童的进一步测试包括发展更复杂的手势和语言技能以及学龄前能力，如基本数学技能、工作记忆和语音意识。通过大多数(46个参与家庭中的43个)无条件同意继续研究，通过已经连接两个赠款部分的申请者之一(Ritterfeld)的资金，以及通过与BMBF(Lizkowski)资助的另一个正在进行的赠款项目的连接，继续纵向方法是可行的。此外，我们计划对已经收集的数据(Rohlfing)进行额外的分析。

Continuation of an already DFG funded grant to conduct a longitudinal study with children between 12 and 30 months is proposed up to an age of 6 years in order to a) further validate hints on the possibility to identify language disorders at a preverbal age; b) investigate determinants on the association of gestural and linguistic skills in more detail; and c) validate results within a bilingual sample. Further testing of children includes development of more complex gestural and linguistic skills as well as preschool abilities such as basic mathematical skills, working memory, and phonological awareness. Continuation of the longitudinal approach is feasible through unconditional agreement of most (43 out of 46) participating families (Dortmund) to continue in the study, through funding from one of the applicants (Ritterfeld) that already bridges the two grant parts, and through the connection to another ongoing grant project funded by BMBF (Liszkowski). Moreover, we plan to conduct additional analyses of the already collected date (Rohlfing).
